O-(3-cyanophenyl)dimethylphosphinothioate, also known as cyanofenphos, is an organophosphorus compound with the chemical formula C10H10NO2PS. It is a colorless to pale yellow liquid with a pungent odor. This chemical acts as an irreversible inhibitor of acetylcholinesterase, an enzyme responsible for breaking down the neurotransmitter acetylcholine in the nervous system. As a result, it disrupts the normal functioning of the nervous system, leading to its use as an insecticide and acaricide. Due to its high toxicity, it is classified as a Schedule 1A pesticide by the United Nations Food and Agriculture Organization, indicating that it poses a high risk to human health and the environment.

3186-34-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3186-34-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,8 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3186-34:
(6*3)+(5*1)+(4*8)+(3*6)+(2*3)+(1*4)=83
83 % 10 = 3
So 3186-34-3 is a valid CAS Registry Number.

A concerted mechanism for the transfer of the thiophosphinoyl group from aryl dimethylphosphinothioate esters to oxyanionic nucleophiles in aqueous solution

Onyido, Ikenna,Swierczek, Krzysztof,Purcell, Jamie,Hengge, Alvan C.

, p. 7703 - 7711 (2005)

Earlier work on the hydrolysis of aryl phosphinothioate esters has led to contradictory mechanistic conclusions. To resolve this mechanistic ambiguity, we have measured linear free energy relationships (βnuc and βIg) and kinetic isot
